Subject[PATCH resend #1] fix cu3088 group write
Hi Linus, Andrew

The current cu3088 ccwgroup write code overwrite the last char of the
given arguments. This following patch fixes the problem. It is been
tested and applies on latest bk.

memcpy is not an option since the string will be used with strncmp with
a length > BUS_ID_SIZE.
Please apply.
